Abstract:Regardless of all the improvements in design and technology, there can be no doubt that the longevity or durability of concrete structures may be affected by certain imponderables. Chemists and designers are still searching for solutions in their own special fields when, perhaps, the real answer lies elsewhere.

Concrete is generally allotted two stages: design, and batching and mixing. This paper sets out to show the placing of concrete as the third stage, of importance equal to that of the other two.
